What if there were Slime Science resources that one could get directly from slimes? Say, Tangle slimes could produce a Big Petal, Crystal slimes a Crystal Shard, that sort of thing. Each slime would have a small chance to produce said resource once a day, with a potential upgrade that could be added to the Corral to make the slimes produce the resource at a slightly higher rate. Could be used to make a bunch of new items.
